I’m kinda surprise nobody mention that Edelgard is basically Olga Marie Animusphere if Olga had survive past the prologue and became even more fucked up.
White hair, red tights, noble family of the highest order, TsunTsun, and fucking insane

The game even make a big deal about all those family crest and nobles and families and all that holy boly Nasuverse bolonie booie about magic.

If Olda survived, were she to accompany Gudako and Mashu on their adventure, I think she would glow to become way more understanding, at the very least... Also, thanks to Riyo's manga, I really hope we can bring her back eventually.
